Definitions

  • the invention relates to a slot die for extruding flat films with an upper and lower die lip, which delimits the outlet gap upwards and downwards, according to the preamble of claim 1.
  • Such wide slot nozzles are used in the production of plastic webs.
  • At least one of the two nozzle lips is designed to be flexible in order to be able to subject the outlet gap to fine adjustment and regulation in accordance with the measurement data obtained.
  • the adjustable lip is usually formed by a material taper, via which length-adjustable actuators exert a corresponding bending load on the at least one adjustable sealing lip, in order to thereby effect the adjustment.
  • the outlet gap can be enlarged and reduced, for example, by means of thermally heating and thus length-adjustable actuators.
  • the gap-regulating tool lip can also be carried out, for example, by means of a field translator based on the piezoresistive effect.
  • an extrusion slot nozzle which comprises a plurality of passive actuators acting on a flexible band, a further plurality of lamellae arranged movably between the band and the flexible lip Initiation of the positioning force from the flexible band to the lip are provided.
  • DE 37 31 961 A1 discloses a device for adjusting the gap of a nozzle by means of a thermal bolt, which also includes air cooling for faster cooling of the thermal bolt and thus for contraction of the actuator.
  • thermal bolt For this purpose, axial cooling channels are provided in the thermal bolt, by means of which a corresponding amount of cooling air can be set via a connectable compressed air hose and the cooling capacity can thus be varied.
  • the cooling air is generally compressed air.
  • the thermal bolt itself is again designed as a conventional tension / compression element.
  • a general problem for systems of this type is that, with increasing winding thickness of the plastic film web, thick or thin parts occur in the winding station due to existing thickness variations of the plastic film, which result in a completely uniform winding without any thickening or elevation over the entire film ⁇ Do not allow line width.
  • the main problem here lies in the range of influence of an actuator, which is too wide for optimal film quality, on the one hand in the spacing of the active actuators of over 25 mm, which is wide for geometrical reasons of arrangement, and on the other hand in a massive design of the flexible lip and the result thereof resulting bending line is justified.
  • the area of influence related to the final film is more than 230 mm with an actuator distance of 28 mm, whereby the bending line means that flexible lip can be influenced at least two neighboring zones on each side.
  • the slot die should also be as insensitive as possible to environmental influences in order to increase the functional stability.
  • a sufficiently high setting speed of the actuators is nevertheless to be ensured in order to achieve the desired thickness profile.
  • the task is saying 1 bwz. 18 specified features solved.
  • Advantageous refinements of the invention are specified in the subclaims.
  • forced cooling is also provided in spite of the significantly increased number of adjusting bolts, by means of which a short adjusting speed of the adjusting bolts can be achieved.
  • the slot die according to the invention is thus characterized, inter alia, in that, in order to increase the number of adjustable actuators 13 with respect to the total length of the nozzle lips 3, 5, at least two adjuster elements 13 lying adjacent to one another are assigned a common presetting device 37, and / or two in the longitudinal direction of the Outlet gap 1 successive adjacent actuators 13 are arranged or terminated at their end facing away from the adjustable nozzle lip 3, 5 with transverse offset to the longitudinal direction of the outlet gap 1 and thus the associated presetting devices 37 of two adjacent actuators 13 with corresponding transverse offset lie to one another and / or both nozzle lips 3, 5 are provided with actuators 13 which are adjustable in length in such a way that the actuators 13 assigned to one nozzle lip 3 are offset relative to the actuators 13 assigned to the other nozzle lips 5 are net, and that at least one of the two nozzle lips 3, 5 acting actuators 13 is assigned a preset 37.
  • a coarse or presetting device is assigned to the adjustable actuators or at least one of the two lips (on which the adjustable actuators may not also directly engage).
  • the slot die according to the invention has very particular advantages when used in stretching plants in the production of plastic films. However, the advantages are still surprising for the production of a so-called cast film.
